GLAZED ROOF STRUCTURE.

To all whom it may concern:

Be it known that I, HENRY T. THOMAS, a citizen of the United States, and a resident of New York, Manhattan borough, in the county and State of New York, have invented certain new and useful Improvements in Glazed Roof Structures, which improvements are fully set forth in the following specification.

This invention relates to improvements in roof-structures, and particularly to glazed roof-structures wherein are embodied socalled glazing-bars or astragals for supporting panes of glass; and its object is to provide a roof-structure of the character above indicated, which shall be durable, efficient and reliable in practical service; which shall embody novel features pertaining to the seating of the panes of glass made use of; and which shall possess certain well-defined advantages over prior analogous constructions.

The invention consists in the combinations, details and parts whereby, together with the novel disposition and relative arrangement of said parts, the attainment of the foregoing object is rendered practicable, all of which will be hereinafter more specifically referred to and set forth in the ap pended claims.

The invention is clearly illustrated in the accompanying drawings, wherein similar reference numerals denote like parts throughout the respective views, in which:

Figure 1 is a view in perspective of a fragment of a glazed roof-structure embodying my said improvements. Fig. 2 is a detail end elevation of a fragment of the construction shown in Fig. 1, the scale being enlarged. Fig. 3 is a view similar to Fig. 9., showing the cushion which I make use of with certain of its constituent members tilted somewhat upwardly, as the same may appear prior to the application of said cushion to practical purposes. Fig. 4 is a view similar to Fig. 3, showing said cushion with its summital constituent member arched somewhat upwardly, as the same may appear prior to the application of said cushion to practical purposes. Fig. 5 is a view similar to Fig. 2, showing a slight modification of said cushion.

In a general sense my present invention comprises a medium for cushioning a pane of glass on the upright side-flange of an astragal, said medium being interposed be- Specification of Letters Patent.

tween said side-flange and said pane of glass, yieldable, mainly within the plane of said side-flange, for conformation to the surface, whether regular or irregular, of the glass contacting therewith, and correspondingly providing a continuous seat for said pane of glass.

In carrying out my invention, reference being had to the accompanying drawings, I make use of an astragal 2, having opposite side-flanges 2, 2", rising upwardly therefrom, and a central, upright web 3, arranged midway bet-ween said side-flanges; panes of glass 3, 3", normally tending, by their own gravity, to seat, respectively, on the sideflanges 2, 2, at the upper edges thereof; and a cap 4, which straddles the web 3, and bears at its opposite edges on the adjacent margins of said panes of glass, said cap being held in position by nuts l, carried by tie-bolts l", which project at intervals along and upwardly from the web aforenamed, through the cap 4, and are duly threaded, each to receive one of said nuts, all as in common practice. I further interpose between the upper edges of the side-flanges aforenamed, respectively, and the panes of glass thereon, a cushion, yieldable, as hereinbefore stated, for conformation to the surface of the glass contacting therewith, and correspondingly providing a continuous seat for said pane of glass, said cushion being here shown as approximately in character the form of a plicated bead, and comprising a base member 5 and a summital member 5, integrally connected, at the reverse edges, as 6, 6, thereof, by an intermediate memher 5.

The cushion fiforenamed, and of which connected members aforenamed essentially constituting the same, is formed by appropriately folding longitudinally and approximately upon itself, a strip of yieldable material, preferably copper, zinc or aluminum, in thin sheet-form. One of the cushion members aforenamed, as 5 or 5, is extended slightly beyond its neighbor or neighbors, and merged into a down-turned sheathing or facing segment for either the inner or outer face of the adjacent sidefiange of the astragal, as the user may elect. However, as illustrated in the drawings, I contemplate accordingly extending the cushion member 5 and merging the same into a down-turned facing segment 6", which serves, in practice, the dual purposes of shielding the cushion proper aforenamed, at one side thereof, and more or less of the inner face of the adjacent side-flange of the astragal.

The segment 6 may terminate at any desired point within the adjacent astragal channel, although I purpose to continue the same across the base of said channel, up-

wardly along the adjacent face of the web 3,

across the top thereof, downwardly along the opposite face thereof, across the base of the opposite astragal channel, thence upwardly along the inner face of the opposite sideflange of the astragal, and merge the same into a cushion corresponding to the cushion firstherein referred to, said segment, accordingly, conforming to and shielding the entire top surface of said astragal, between the side-flanges thereof. Again, I contemplate correspondingly extending the member 5, and merging the same into a. down-turned facing segment 7, which serves to shield the outer face of the adjacent side-flange of the astragal; and, by preference, this segment 7, is in turn merged at its lower portion into a condensation gutter 7 which runs parallel with the astragal aforenamed, at one side thereof, and is inclined accordingly, this gutter feature of the construction being produced by turning the segment 7 laterally and thence somewhat upwardly, as clearly indicated in the drawings.

lVhere both of the segments 6 and 7 are employed, the same projecting uniformly as to direction from the cushion proper aforenamed, and occupying suitably-spaced, parallel planes, they serve to engage the adjacent sidefiange'of the astragal after the manner of a clip; and, during the erection of the structure, facilitate the adjustment of said cushion for service and its retention in position on the side-flange of said astragal.

The cushions for the opposite side-flanges of the astragal, with or without the outer facing segments thereof, may be formed from a strip of material of sufficient width to extend along and form a facing or lining adapted to shield the entire top surface of the astragal aforenamed, between the sidefianges thereof, with said cushions overlying the upper edges of said side-flanges, respectively, all approximately as hereinbefore specified; or, each cushion may be formed from a strip of material of sufficient width to provide one or both of the segments 6", 7, as may be found desirable in practice. Again, the constitutent members of the cushion aforenamed, prior to the placing of the glass on said cushion, may vary widely in the matter of cross-sectional contour, or normal position, each as compared with the cross-sectional contour or normal position of its neighbor, or any of its neighbors. For

example, as shown in Fig. 3, the member 5 assumes, approximately, a horizontal posi tion, while its neighbors 5, 5, are jointly tilted somewhat upwardly therefrom; and, as shown in Fig. at, the members 5', 5, jointly assume, approximately, a horizontal position, while the member 5 is arched somewhat upwardly therefrom, and hence varies in cross-sectional contour as compared with the cross-sectional contour of either of the members 5, 5".

In the modification shown in Fig. 5, the member 5 may be assumed to have been severed centrally and longitudinally, thereby forming reversed portions,hook-like in crosssection, which freely interengage each other under normal conditions, and whereby one hook-like portion may be readily detached from the other hook-like portion, as will be clearly understood. This feature of my improved construction will be found advantageous where it is preferred to form the segment 7, with the gutter 7 conjoined therewitl, separate from the segment 6", with the cushion conjoined with the latter.

The cushion aforenamed, when applied for service, overlies and extends along the upper edge of the side-flange of the astragal 2, with a facing segment, as 6" or '7, projecting downwardly therefrom, or opposite facing segments, as 6 and 7, projecting downwardly therefrom along suitably-spaced parallel planes, one or more of the constituent members of said cushion being more or less separated from the other or others, as indicated in Figs. 3 and a, said cushion accordingly, and to all intents and purposes, being situated and performing its function mainly within the plane of said side-flange. A pane of glass is then placed in position flatwise on said cushion, with the result that the latter, under the weight, and for conformation to the contacting surface of, the glass placed thereon, yields and provides, mainly within the plane of said. side-flange, a contin uous seat for said pane of glass.

While, in the formation of th cushion aforenamed, I prefer to employ copper, zinc, aluminum, or a material of similar character, in thin sheet-form, it is evident that a thicker material, as of the character of lead, in sheet-form, may also be used to serve the purposes intended.

Attention is here called to the fact that under no conditions of the cushion aforenamed, whether continuously and uniformly depressed, as where the surface of the glass contacting therewith conforms to a true plane, or more or less depressed at varying intervals therealong, as where the surface of 125 the glass contacting therewith is irregular, is there an open space left in my improved cushion by way of which cinders, or the like, may freely pass from either side of said astragal flange to the other side thereof; and 139 the lodgment of cinders, or similar foreign substances, between the constituent members of said cushion is further largely prevented by the employment of the shielding segment 6".

It will be seen that my improved glazed roof structure is well adapted for the purposes for which it is intended, and further that the same may be modified to a considerable extent, particularly as regards the munber of the constituent, connected members comprised in the cushion aforenamed, the cross-sectional contour of any of such members, the relative normal position of each with respect to its neighbor or any of its neighbors, and various min r details of the general construction, without departing from the spirit and principle of my invention.
